MACHINE FOR MAKING- AND FILLING PACKETS.

Application filed January 18, 1923. Serial Ito. elects.

To cllwham it may concern:

Be it known that I, ALBERT DAY, 21 subject of the King of, GreatBritain, residing at 53 -Winsha1n Grove, London, S. W, 11, 5 England,have invented certain new and useful Improvements in Machines for Makingand Filling Packets, of which the following is a specification.

The subject of this invention is a machine for making and fillingpackets with. tea, to-

bacco, powders, seeds, or other materials, the said machine being ofsuch construction that if so required it can be used for the manufactureof paper bags-without filling them. The main objects of. thisinventionare to make and fill each packet at a single filling station in themachine, whereby the mechanism therefor is concentrated and reduced tothe minimum number of working parts in contact with the packet, and toproduce filled packets at a very high speed, while minimizingthe risk ofspilling the material being charged.

According to this invention a set or each set of the principal operativeparts of the machine, that is, the funnel, rammer, folders for closingthe top and bottom of the bag,

the mould, and ejector platform, are arranged in vertical relation to-each other so that two cycles of operationscan proceed simultaneously,one cycle comprisiiw the formation of the tube of paper or the like onthe stem of the funnel, closing the bottomof said tube to constitute abag, liftingthe rammer in the tunnel to allow the whole charge to fallinto the bag while the bag is still on the funnel, transferring. thecharged bag to the mould, and ramming the charge before, during or aftersuch trans- 40 fer, while the other cycle comprises folding the top ofthe last preceding bag to form a packet in'themonld, lifting the mouldclear of the said packet, which then lies on the ejector platform at thebottom of the mould,

andejecting the said packet laterally before the mould returns.

The formation of the paper tube on the funnel stem is accomplished inthe usual way by a folding box advancing to embrace the stem or funnel,the edges of the wrapper or sheet of'paper or the like, one of whichedges has previously been coated with an adhesive substance, being thenturned in and rubbed toseal the tube. f 'l.he folding or turning in ofthe part of the tube project ing below the stem of the funnel is alsoeffected as usual by reciprocating members or folders consecutivelyadvancing towards oracross the axial line of the tube, but the firstfolder according to this invcnco -tion has four functions, nainely,tomake the first fold or ply of the bag botto1n,to support the saidfoldand close the outlet of the funnel while the full charge is beino;dropped'on to it, which takes place Wl the; other folds are beingmade,to provn a backing or support during the action at the second andthird foldersand to control the first fold and prevent leakage of thematcrialinto the ears of the packet, this Io control: continuing untilthe fourth folder comes into action. The fourth folder has a movementin" an approximately rectangularpath, nzunely, forward across the bag;downward with the bag through the mould, to which is slotted to givethis folder a pas sage, thenbackward leaving'the filled bag resting onthe ejector platform, and upward to the position at-which it begins itsfor Ward stroke, thus continuing'the control of so the bag bottom duringits transfer from the funnel to the ejector platform.

Themould may comprise a movable inner plate supported'by springs, whichfaci tate the entry of the filled bag therein, and enfig, sures thatfirm packets of uniform size for one adjustment are produced by thismachine, the size of the packets being however capable of, somevariation according to the adjustment as required of the said movableplate. a I

The present invention also avoids the difficulties arising in theoperation. of machines in which empty bags are placed in the mould,where 'unlcss'the bag is perfectly made, particularly at the corners,and prcrented to the mould in perfect alignment, the bag is liable tocrumple, when the machine has to be stopped to remove it, and the chargeof the imperfect bagmay be wasted, whereas in the present machine shouldan imperfect bag reach the mould, the mould tends to straighten it. Themachine can also be readily adapted by small adjust ments or exchange ofworking parts for we making: packets of different sizes and shapes.

In order that the said invention may be clearly understood and readilycarried-into effect, the same will now be described more fully withreference to the accompanying drawings, in which Figure 1 is a frontelevation of a machine for carrying out the above process.

The reference numeral 11 indicates the framework of the machine, onwhich are upward extensions 8% supporting a table 80 and connected by astay rod 'iillars Q50 and 251 connected by a stay rod 259 and carryingbrackets 66 at each side of the machine. Stay rods 65 connect thebrackets 66 with the extensions 8 12 indicates the driving shaft, onwhich are mounted a fast pulley 13 and a hand wheel 15 (see Figure 2).The loose pulley 1 1 runs on a bush or sleeve 19. On the driving shaft12 is a toothed pinion 22 (see Figure 5) in gear with a toothed wheel 23on the first motion shaft 24. The rotary shaft 13 1- is driven through awheel 133 also engaging the wheel 23, and the 30- .tary shaft 136 isdriven through a wheel 135 engaging the Wheel 1233. The shaft 28 isrotated step by step by pawls actuated through connections from a crankon the shaft 2d as hereinafter described, and the shafts 3? and 50 aredriven from the shaft 28. Stay rods 58, 62,101, L11, 1 19 and 217 areutilized for the attachment of movable parts of the mechanism. Thelormcrf is shown at 71, the upper parts of the tour folders at 16.3,202, 203 and 205 respectively, (see Figures 9, 12, and 13) the back wallof the mould at 223, (Figure 15) and the rammer at 260. The means forobtaining the required movements will be understood from the followingdescription.

In a bearing 16 a roll of paper or the like 17 is supported by a pin 18therein, and the said roll 17 is freely rotatable to allow the paper tobe drawn off. A bracket 20 provides a bearing for a second roll of paper21, (Figure which is only required in cases where two thicknesses ofpaper are used on each packet made, for example an outer layer which mayexhibit the name of the trader in such packets, and an inner layer oftissue paper or greaseproot' paper to protect the contents. W hen tworolls of paper are used, the lower one is set a little to one side ofthe upper one in order to leave a narrow space along one edge of theouter sheet of paper clear for the reception of gum or other adhesivematerial for securing the packets when made. Although the machine canthus obviously be used for making packets having two or more layers ofpaper or the like, in the following descrip tion it is assumed that theroll 21 is absent and that only one thickness of paper or the likeemployed.

The roll '1? is held in position onthe pin 18 by cones and 3&1; and byturning the hand wheel 591116 pin 18 with the cones and roll can bemoved laterally in the machine.

Un the shaft 2 1 is a crank arm 25 (Figure which through a rod 26 isadjustably connected at 337 with and oscillates a segment: 27 loose on ahigher shaft 28, on which latter shaft is secured a ratchetwheel 30. Thesegment 27 carries one or more pawls, which in the case of more than onepawl being em' ploycd are of slightly different lengths.

Preferably three pawls are employed as -out employing very fine teeth onthe ratchet wheel, as teeth or coarser pitch are found to wear longer,and to allow the 'pawls to engage more easily. On this" shaft 28 is apulley or chain wheel 3operatively connected. by a belt or chain 35 witha pulley menace or chain wheel 36 on another shaft 37 in the bracket 66,which shaft 37 is thereby caused to impart as intermittent rotation to apaper feed drum 38 thereon. (shown in dotted lines in'Figure 6). I

From the roll 17 the strip of paper or the like, the path of which isindicated in dot-and-dash lines, is drawn off by the pull of the drum38, and on the way to the said drum it passes over a roller 40 ofagreater width than, thatof the paper, which rollor 40 is freelyrotatable, and in contact with a. small roller 41 which may be made ofrubber, 'flange of a disc 42 (Figures 4 and 5) which dips into a trough13 containing gum or other adhesive material, such adhesive niaterialbeing thus transferred by the disc 42 till to the roller 41 and therebyto one edge of the travelling strip-of paper. The paper then passesbetween the drum 38 and a guide roller 45. p

A hand wheel 49 (Figure 2) on the end of the shaft 28 can be used whenthe for-. ward end of a new roll of paper is to be inserted, for windingthe said paper from the roll 17 to the drum 38. The gumn'iing disc 4:2is carried on a shaft 50 (Figure 6) which is driven by a train ofgearing from the'shaft- 28, and drives the shaft 56 of the roller l1through gears 54: and 55, the proportions of the respective gears beingsuch that the peripheral speed of the roller 41 and disc 42 shall be thesame as that of the paper feed drum 38.

On the first motion shaft 24 is a cam 57 (Figure 4:) with which engagesa bowl b t on one arm of a bell. crank lever 50 on a fixed rod 58, thislever 59 being connected by a rod the stay rod 62. The lever 01 carriesthe shaft 56 of the rubber roller 4-1 and is caused by the operation ofthe cam 57 to lift the roller 41 clear of the travelling strip of paperpassing over the guide roller all! once in each. revolution of the shaft24;, in. order to produce a gap in thestreak of gun'i on such paper atthe part where cut will be required for the purpose of severing aspectof paper from the travel-- ling strip as hereinafter described, this being desirable for the purpose of avoiding clogging of the cuttingmechanism by gum. The roller 4:1 canbe thrown out of action bydepressing the handle 67 (Figures 4: and 6) so'as to lift the curvedlever 61, in order to prevent the said roller 11 from becoininc' stuckto the paper if at, any time the machine is'left (Figures 4t and 6) maybe arranged to rernove superfluous gum from the disc l2.

On the shaft 2% is a cam '72 and on the rod 58 is movable a bell cranklever '73 having at its end a bowl. M engaging the said cam '22 by meansof the rotation of and is also in contact with the.

'thc front wall of the 60 to curved lever 31 pivoted to standing. Ascraper 68 front and inner walls of the box.

On the back of the box 81 is a bracket forming a sleeve 87 through whichworks a rod 88 'arrymg at its front end a plate 90 which in the positionshown in Figure,

(iis in line with the parts 5-32, 82- and forms box, in front of which asheet of paper can be placed. Below the sleeve 87 the bracket also formsa boss 91 through which passes a pin on the rod 85, by which means theoscillation of the level 7 as aforesaid conveys a reciprocatory nmvcmcntto the box 81.

On the boss or sleeve 8? is a spring 93 connected with the rod 88 andtending to pull the said rod forward relatively to the box 81, theforward movement of which rod 88 is limited by a stop collar 94: thereonengaging the rearend of the sleeve 87.

Pivotcd on the brackets 60 are a pair of adjustable oscillating links9?, (Figure 8) and 98 (Figure 7') carrying at their lower ends bearingsin which are pivoted a pair of arms 101, (Figure 8) and'102, totheopposite ends of which is attached the movable blade 103 of the knifeor guillotine.

On a rod 10 1 supported in I the two brackets (30 can freely rotate apair of twoarnied levers, one of which is shown in Figures 4 and 8, suchlever con'i in'ising a lower arm 105 and an upper arm 100. The arm 105carries a blade 10? which in its action is practically a fixed resistingpart, with which the movablc'bliulc 10:5 cooperates with a shearingaction, that is, the movable blade travels in a direction normal to orpcrpeiulicular to the front of the lined blade, but owing to thereceding line of the edge of the movable blade 103 (see Figure?) it isonly cutting at one point at a time. 'lhe roller is journalled in theupper portion of the lever arm 105. A spring 108 secured. to the pin11.0 on the arm 105) is also connested by a pin 109 to the fixed bracket66, and draws the arm 10:3 and roller 45 with therequiredpressurcagainst the feed drum 38, providing suiiicient frictionto draw the Liv . adapted for making to the arm 101 is also secured to astud adjustable in a slot 116 in the arm 106, the function of thisspring being to hold the knife 103 up to the fixed blade 10'? with therequired pressure. A vertical rod 96 (Fig ure 8) carried on the sleeve8? (Figure 4) comes centrally in front of a rod 117 joining the lever101 to its opposite-0r counterpart lever, so that on the return strokeof. the box 81, the lever 10]. and blade 103 are with drawn, when theext length of paper can be fed into position for cutting off. A guideplate 118 is secured to the backs of the levers 10:) to guide the papercoming from the roller 32% into the gap provided by the withdrawal ofthe plate 103, and another guide plate 110 secured on rods 120 in anupward eslcmsion 1 1 of the movable arm 101 dislodges the neat oncominglength of paper from the iifa'tftl l-Lnife member 107, this guide plate113) being recessed to clear the portion of the paper which is gunnncd.

Instead of employing a paper supply roller, a feed roller, and cuttingmechanism as above described, reparate sheets may be successively fedinto position in the machine in any known or suitable manner f'roma pileof such sheets.

The sheet of paper severed as above described rests at its lower edge onledges 122 (Figure 4;) at the bottom. of the front plates 8:3, 8; of thebox 81. and may also be held against the front of the box at one or bothsides by spring lingers as shown in Figure (5. These however may not befound necessary where the packets are made of only a single thickness ofpaper. A stop rod 123 is lined in the framework of the machine; on avertical pivot 121 at the side of the plate 83 is a thrce-armed grippingdevice comprising a curved linger 125, an arm 120 carrying at its end. abowl 127 normally pressed by a plate spring into such a position as tocause the finger to press againstihe front face of the paper, and an armcarrying a bowl 130 adal'ited to engage a cam path on an arm 131tirojecting from the machine fran'ie'vvork, so that on the advance ofthe box the ringer 125 is removed from and releases the paperand on thereturn. stroke of the be): the bowl 12? engages the end of the stop rod123 to open the grip ping device to receive a fresh sheet of paper.

The box 81 carrying the sheet of paper is advanced by the rod 85 so asto cause the plate 90 to press the centre of the sheet of paper againstthe back of the downward extension 71 of the hopper or funnel '70, whichis secured in the framework of the machine as shown in Figure 1, thisdownward extension, which for making square or oblong packets is ofrectangular cross section, being hereinafter called the former.- Themachine can, however, be readily packets of cylindrical 'acrossthebottom of the or 0th r desired shape. The movement of the roe 85continues so that while the resistance of the former prevents thefurther advance of the plate 90 and the spring 03 is extended by theadvance of the rod 88, th flanged plates 82, 83 secured to the backportion 81 of the box continue to advanc each side of the former, andpress the t side portions of the paper, which o released by the finger125, against the walls of the former so that the vert cal. edges of thepaper project past and in front of the former, and the leading portionsof the paper are then flattened over each other by the followingmechanism The Wheel 23 on the shaft 2 1- which previously describedreceives motion from the driving shaft 12 also engages a carrier Wheel.1233 on a shaft 134 (see Figure which imparts rotation by means of awire" 135 to a shaft 136, on which shaft are i cams 13? and 1-38 (seeFigure 1.}. The cam 138 at the left hand side of the machine engages abowl 139 on the end of one arm 140 of a bell crank lever fulcrumed onstay rod 141, the other arm 1 12 of which. lever is connected by auniversal joint at 143 to a rod 144 which is in turn connected by auniversal joint at 1&5 to a lever 1 16 pivoted at work n um of themachine (see Figures 1, 2, 3 and plate'15O (Figures 1 and 4). A s 1 169anchored to a stay rod 14-9 the bottom the machine is also connected tothe outer end of the arm 140 to hold the bowl 13.) in contact with thecam 138. At the opposite or right hand side of the machine the cam 13?through a series of connections similar to those just described with theaid of reference numerals 139 to 14:8 actua'tes a similar flat plate151. The flat plate comes first into action and the plate 161 followslaying the guinmed edge over the other edge. Be-

The paper now constitutes a tube of square cross section, the lower partof which projects below the bottom and it is. now necessary to fold thelower part inward to make a bag bottom, for which purpose four foldersare caused to pass former consecutively, each producing one fold in thepaper. The folding mechanism is preferably ar- 11-7 to a bracket 148 onthe frame- 9, a rubber 152 comes of the former, f

ranged to close inlthe top of a lower bag already filled at the sametime as the bag bottom is formed in the paper on the former. Aconvenient arrangement of mecha nism will now be described for makingpacts-2t tops and bottoms of the single ear type, that is, in which theextremity of the pression spring; 170 one end of which is se-'- cured toa staple on the table 172 on the frame of the machine, the other end ofthis spring pressing against a swivel stud 1'13 working in the lever168. Thetop of the lever 168 is connectedlby a link 174 to a stud 175(Figure 4i) in the sliding bar 165 (Figare 12), [it the operative-end ofthe bar 165 two suitably shaped blades'176, and 1?? are secured to twooscillating brackets respectively numbered 178 and 180. At the rear endof each oscillating bracket is an. arm, these arms beinpg'numbered 181and 182, The upper arm 181 hasthe required oscillating movementimpa'rte'd to it by a bowl or runnerflSo" mounted on its endand hearingagainst a fixed cam path on the bracket 1418. As the blades 176 and 177are advancing they are normally inclined, but turn to a horizontalposition just prior to reaching the end of their stroke, so that theedges of the blades 176, 177 first engage the eldges of the paper, andin consequence of tie movements of the blades, the whole surface of eachblade is in engagement with the paper when the first fold is completed,and these blades can rcmain'in position while the second and third foldsare being made, being withdrawn whengthe fourth or last folder comesinto action.

ably shaped folder block 202, which swings across the lower end of theformer 71, forming'the second fold. The cam 19-1 is similarly connectedby the arm 209 withthe folder block 203 to make the third fold,

The fourth folder block 205 (Figure 1-8), when the third folder 203 isat the end of its folding-- stroke, comes up alongside the partly foldedsheet of paper, and hips the triangular folded portions thereof tightl'against the sideof the saidblock 203. This fourth folding block 205 isT shaped in plan, so that as the straight front portion travels acrossthe bag, the rear ornarrow portion 206continues to hold down the lastfold, remaining in contact with the bag until it. is filled anddelivered to the mould into which the bag next passes, and until the.mould returns to its lowest position. This folder is operated by thefollowing mechanism: v

. On the shaft 24; are two cams 207 and 208,

the first cam 207 arranged to give a horizontal moi-'ement and the'cam208'to give a vertical'movement. The earn 207 acts bycmeans of a bowl210 011 the short arm 211 of a bell-crank lever pivoted onthe rod 58,the

long" arm 213 of which lever is linked by a forked lever 21% to pivotalconnections on the'back of the part 206, a bracket 215 depending fromthe part 80 passing through the slot in the said lever 21s to guide itin its movement. A spring 212 connects the arm 213 with the machineframework to hold the bowl 210 in contact with the cam.

A three-armed lever 216 pivoted on a stay rod 217 is pivotally connectedwith a rigid curved tail-piece 218 on the folder block 205, and carriesa bowl 220 engaging the cam 208, and is connected withthe machine frameby a spring 221 to maintain such enimpart to the folder block 205 amovement in an approximately rectangular path, namely, forward acrossthe bag, downward with the bag; through the mould, then backwardloavingthe bag resting on the station and platform or bottom plate 224 of themould, and upward to the position at which it begins its forward stroke;I

'Where itis required to make bags with ends of the double ear type, thefolder above described as the fourth folder is timed to act immediatelyafter the'first folder, the remaining folders then forming the cars. Thesaid fourth folder must therefore have an additional stroke, namely,withdrawing from the path of the usual second and third folders, andafter they have fulfilled their function returning to s u 'ipoi-tthebugt This additional stroke can be obtained by the use of a suitablecam.

(Figure l), the lever being held to its work by a spring 294 (Figure 4).The lateral motion thus given to the rod 281 is converted into anindependent vertical motion of the plunger 261 relatively to the ramineror Stamper bar 260. The ravmnier is moved by the cross head. Themeasured charge is supplied to the hopper While the ruinnier is near thebottom oi its stroke, and on the rmnmer rising it ellovvsthe charge tofell into the bag; the rammer then descends, the point of the plunger261 breaking up any central mound or elevation on the surface of thecharge and distributing its components to the sides or corners of thebag, after which the end o't-tlie main renimer overtaking the pointflattens the charge ready for the folding overv oi? the top of the bugto make a packet, the inner wall orplete225 of the mould, which asaforesaid is supported by springs 239, giving vvsyslightly to avoidexcessive crushing of the charge, which in the case of tee is liable tobreak it up into dust. The said inner plute may be pressed in by a cumor other convenient means, after the ruminer has been withdrawn, toensure firm packets of uniform size are produced, a further movement ofthe cam releasing the pocketfrom pressure.-

Vlhen this machine is used to make paper boos only, the mould can beremoved and the rammer may or may not be used to remove the bags fromthe former? The empty bags will be token out of the machine Withoutbeing; subjected to the action of the lower. plates or arms of thefolders, which ore only required for closing filled packets.

The bag when filled will usually leave the .tbrniei" and descend intothe mould by the hire of he stuinper on the top of the :lllll in triotunnel or former, but means such as those shown in Figure 16 may beprovided for ensuring the disengagement of ill? lllii the bag from theformer. By the extension of the shaft 161 to the table 172 a guide 18provided for aslecved bracket 295 a forked arm 296 of WlIlCll engagesthe guide with a bellcrank lcver-299 on the stay rod 217 to Workthis'ejector, which descends at the same speed as the descending mould.As soon as the rammer'reaches 1n its down-stroke the square part of theformer, the next charge can be dropped into, thefunnel'at the head ofthe former, Where it remains by reason of the rammer being of about thesame diameter as the former, until the rammer has completed itsdoWnstro-ke and rises again, this period being equal to about half arevolution of the main driving shaft of the machine, so that accuratetiming of the feed of tea to the funnel is not so necessary as is thecase in other packing machines. By this arrangement the running of themachine" at a high speed is greatly facilitated. On the, rammer risingto the position in which its operative part is at or near the bottom ofthe former, another sheet of paper can be folded and sealed on theformer. The last folder meanwhile descends further and clears theslotted mould and bracket 224 leaving the filled bag resting on ledgesat or below the bottom of the mould; the said last folder is then drawnback, raised to its first posi' tion opposite the space between theformer and the mould, and in' its turn advances to give the last fold tothe top of the filled packet and the bottom of thefollowing bag, afterthe other folders have operated. The

. mould then rises to receivethe next bag,

leaving the filled packet under the last folder to be transferred bysuitable ejecting mechanism to a belt, trough, or labelling machine.

in some cases it may be found advantageous to make the mould stationary,and

till

to cause the former to rise and fall for the purpose of transferring thebag to the mould.

The finished packets may be ejected from the machine by any suitablemeans, as for example by that now to be described: On the machine frameis pivotedat 301 (Figure 2) a lever 302 held in position by a spring 303and carrying a bowl 304 engaging a cam 305 secured on the Wheel 23 whichis mounted on the shaft 24, to which lever 30% is pivoted a bent plate306, which has a. front flange 307 (Figure 17) which pushes the filledpackets off the platform 224 located below the mould. lnorder to facilitate the operation of the machine at a high speed, the ejector plate 306mo es on a rec tangular path, hlso by so doing it avoids disturbing thenext packet which immediately takes the place of the one thus ejected,until the folders have closed in the top of the said next packet, thatis, after pushing off a packet the said plate 306 descends,recedes,.rises', and then is ready to advance again. Mounted,on theshaft 136 is a'cam (not shown) engaging a bowl 310 on a lever 311adapted to rock on the rod 141 and connected by means of suitable linksand universal joints to the ejector plate 306 to give it a rising andfalling movement, its advancing and receding movements being effected bythe cam 305.

When the packet is pushed off the plate 224: it enters an open-sided boxor tumbler 312 one end of which is pivotedat 313 to the machine frame sothat the said box or tumbler can turnthrough an arc of 90, degases, thatis, it assumes a vertical position to receive the packet. and swingsinto a horizontal. position to place the packet in positionfor beingdischarged through the I in the lowered position. The pusher plate 318is reciprocated in relation to the trough 319 to discharge the finishedpackets, by a lever 320 operated by a face cam 321 on the shaft 24:.

In order to prevent the feeding of the paper from continuing in theevent of? a failure in the supply of the. tea or other material to bepacked, a balanced feeler resting on the said material in the funnelportion of the former may be employed to control mechanical orelectrical devices for throwing out of action the pawls of the papcrfecd drum when the supply fails; or the pawls-may he normallydisengaged, and only come into engagement as each charge- -is delivered.owing to the action of the feeler or the charge in falling into thefunnel effecting the engagement. illustrates an example of mechanism forthe above purpose. in which a flap 322 is hinged on the edge of thehopper T0, this flap hav Figure 3.0 v

ing a pendent tailpiece 323 connected by a ure 20 is shown a rising andfalling rod.

326 which is connected. at its lower end by an ion lifted by means 'of aspring 330. To the upper end of the sliding rod 326'is connected aradius bar 331 forming a cam path.

W'henfhe flap 32?. drops below its normal position by reason of theabsence of the charge, the fail-piece is thereby acfuated to rock thepawl 325 so that the said pawl" engages the projection 333 on the bar326 and prevents the radius bar 331 from being-- lifted clear of theawls 31, 32, 33 thus stopping the feed the paper. The said lifting ofthe flap 332 may be efi'ected by a cam 334: on the shaft; actuating alever linked by a rod 336,lo the tailpiece 323.

The radius bar 331 can be lifted if required by means of a shaft 338(Figure 2) actuating a cam 339 which engages a projection on the bar326, this shaft 338 being moved by either of the handles 29, 39.

The machine may comprise a single former and mould with their accessoryworking parts, or two or more sets of formers and moulds may be embodiedin one machine.
